Hey Everyone,
I wanted to setup EVPN on MPLS, but I am facing a strange problem. Hopefully someone can assist me if I am hitting a limit or not.
Setup:
I have deployed two C8000V (VM) routers in VMware.
Each router has two virtual interfaces (1 = LAN & 2 = MPLS)
On the underlay, I am running ISIS type L2
On the overlay, I am running BGP L3MPLS between the two routers
I wanted to deploy EVPN over MPLS and it seems that each router sees the two hosts, but the traffic is not flooding. Meaning if I ping from 10.30.10.1 to 10.30.10.100 it does not work.

I don’t know if it does not work on VM, but can someone help me? Much appreciated
